build

Spend one work step on a building type at the agent’s current node. First call lays the foundation; subsequent calls advance the same in-progress build until it completes. At most one instance per (buildingType, node) is allowed: laying a fresh foundation is rejected with DuplicateBuildingAtNode when another non-destroyed instance of the same type already occupies the node (yours or another agent’s). Different types may share a node; build elsewhere to add a second of the same type. Queues a BuildStructure command; the resulting building.progressed event (or building.constructed on the terminal step) arrives on the agent’s event stream once the tick lands. Costs per-step stamina + materials.
